RAILWAY-RAI L CHAIR.

SPECIFICATION forming part of Letters Patent No. 469,485, dated February23, 1892.

Application filed July 24, 1891. Serial No. 400,534. (No model.)

To all whom, t may concern:

Be it known that I, WILLIAM HARRY MATT- sON, a citizen of the UnitedStates, and a invented certain Improvements in Railway- Rail Chairs, ofwhich the following is a speciiication.

The object of my invention is to construct an improved railway-railchair which can be readily applied to the rail and which will hold therail firmly in position, as fully described hereinafter.

In the accompanying drawings, Figure l is a transverse sectional view ofa railway-track, showing my improved rail-chairs. Fig. 2 is an enlargedside View of the improved chair,

showing the rail in section. Fig. 3 is a side View of the chair, showingthe same open ready to receive the rail. Figa is a detached perspectiveview of the two parts of the chair. Fig. 5 is a perspective view showingthe chair open,'and Figs. 6 and '7 are views illustrating modificationsof my invention.

A is a rail, which may be of any form for use either on steam or streetroads, the web a of the rail having a series of orifices a' at intervalsthroughout its length.

B is the chair, which is mounted on a crosstie D, as shown in Fig. 1,and consists of two castings or forgings E F, the part E havinga footportion e, a head portion f, adapted to one side of the web of the rail,and apin f on said head portion for entering one of the orices a in theweb of the rail. In the present instance I have only shown one pin onthe head; but it will be understood that more than one pin may be usedwithout departing from my invention, and both the base and the head maybe extended as circumstances require, so as to constitute {ish-platesfor the joints of the rails, for instance. The portion E of the chairalso has a pivot-pin g, which passes through an orifice h in the portionF, projections g on this pin passing through slots 7L in the portion F,so that when said portion F is mounted on the pin, as shownin Fig. 5,and then moved to the position shown in Fig. 2, it will be locked to theportion E. The portion F of the chair has a baser' and a head portion j,extending up against the side of the web of the rail opposite the headf, and

it will be noticed, on referring to Fig. 4, that the portion E is cutaway to receive the hub of the portion F, and the latter is likewise cutaway to receive the hub of the portion E. The bolt g, instead of beingcast with the portion E, may be cast with the portion F, or may beindependent of either portion and provid ed With a nut. Any downwardpressure on the rail, as indicated by the arrow, Fig. 2, will tend toforce the bases e and t' outward, and the heads f j will therefore bindtightly against the web of the rail, as also indicated by the arrows inFig. 2. The chair is secured to the tie by spikes or other suitablemeans. The pin passing through the oriiice in the rail prevents the railfrom lifting and also prevents any excessive longitudinal motion of therail, and when the rail is specially made the pins may be form'ed on therail and the chair recessed.

In Fig. 6 I have shown a chair in which I have substituted for the pin fa rib f2, eX- tending into a groove in the web of the rail, and in Fig.7 I have shown a rail having the web tapered from the base to the headof the rail, the heads of the chair-sections being tapered to correspondwit-h the taper of the web, which is sufficient to prevent the rail frombeing lifted from the chair.

I claim as my invention# l. In a rail-chair, the combination of the twosections E and F, pivoted together, each having a base portion and ahead portion, said head portions extending upon each side of the web ofthe rail, the head portion of the section E having a pin cast thereonadapted to engage with an orifice in the web of the rail, whereby therail is locked to the chair, substantially as specified.

2. The combination of the rail having a perforated flange, a rail-chairformed of two sections pivoted together and each having base portionsand head portions, with a pin on one of the head portions extendingthrough the perforated flange of the rail, whereby the rail is preventedfrom being lifted from the chair or moving longitudinally therein,substantially as described.

3. The combination, in a rail-chair, of the sections, each having a baseand head portion and each recessed to receive the hub of IOO the othersection, one of said sections having a hanged pivot-pin and the otherhaving a slotted oriice for the passage and reception of said pin,substantially as specified.

4. The combination, in a rail-chair, of the sections, each having abaseand head portion and each recessed to receive the hub of the othersection, one of said sections having a flanged pivot-pin and the otherhaving a slotted orifice for the passage and reception ro of said pin,substantially as specied.

In testimony whereof I have signed my naine to this speciiication inIche presence of two subscribing witnesses.

WILLIAM HARRY MATTSON.
